Notes:
High pressure toroidal equilibria with εβpol(very-much-greater-than)1 are shown to be violently unstable to magnetohydrodynamic (MHD) kink modes. Here, ε is the inverse aspect ratio of a torus with a square conducting wall and βpol is the ratio of the plasma pressure to the poloidal magnetic field pressure. A broad spectrum of toroidal mode numbers is unstable at large εβpol. These modes grow rapidly, with a very short exponential growth time of the order of the Alfvén time. The growth rate of the kink mode is independent of the magnitude of the resistivity of the plasma. © 1996 American Institute of Physics.
